This is a RFID reader/writer module using the 13.56Mhz carrier frequency. This is the same as the poplar 'mifare' range of RFID cards, as used in London's 'Oyster' scheme and many others. The reader/write module comes with a rigid antenna that conveniently connects to the module with an attached JST terminated lead.
It's obvious, but it's worth pointing out that you can only use this module to write to an RFID card/tag, if the card/tag itself supports it! Please look in the SDK and sample code file for details about exactly which types of writable card/tag are supported.
